. WASTE-OPERATING MECHANISM FOR BASINS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed June 25, 1909. Serial No. 504,223.

To all whom it may concern:

Be it known that I, WILLIAM SYDNEY GRAHAM, a citizen of the UnitedStates, and resident of Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement inTaste-Operating Mechanism for Basins and the Like, of which thefollowing is a description, reference being had to the accompanyingdrawings, which form a part of my specification.

My invention relates to the waste valve for basins and the like and alsoto the mechanism for actuating the same; and has for its object theprovision of mechanism adapted to be disposed below the slab or basintop or back of the splash-board, and which permits of the positiveoperation of the waste-valve; the nature of the media nism being such asto permit of the parts being readily installed or easily removed andreplaced as will more fully hereinafter appear.

In the drawings :-Figure 1 is a vertical sectional view showing theinvention applied to a wash-basin with a portion of the basin brokenaway. Fig. 2 is a detail sectional View taken on the line 22 of Fig. 1.Fig. 3 is a vertical sectional view, partly in elevation, showing amodified form of my invention disposed on the splash-board. Fig. 4, is adetail View showing the means employed to actuate the operatingmechanism for controlling the waste-valve.

I have illustrated a portion of a washbowl A, provided with thedrain-outlet which communicates with the waste-pipe; the drain-outletbeing preferably provided with the perforated cap a, beneath which isdisposed the waste-valve b, which has its seat at the orifice of thewaste-pipe B. I have shown the valve operating mechanism as preferablyinclosed in the tube or casing C, the lower end of which is shown asterminating in a valve-chamber c and the waste-pipe connecting end B. Inthis construction the lower ends of the wall of chamber 0 provide theseat for waste-valve b, as clearly shown in Fig. 1.

With the style of waste-valve illustrated,

it is preferable to employ some means whereby the valve will be guidedin its movements, and for that purpose I provide the cap a with adownwardly extending stem al, which takes into the upwardly extendingtu- The valve operating lever f is pivoted at g, in the methodillustrated, the lever f is mounted within the tube or casin C. Thelower end of lever f is preferably Iaent upward as shown to remain inengagement with or in close proximity to the bottom of valve 6. Theupper end of lever f is preferably formed with the flat surface orcrosshead it, in order to provide a bearing-surface to be engaged by thecam 2' which is eccentrically disposed on the lower surface of the shankof member or knob j, which latter is adapted to be turned within itscasing D. \Vhere the lever is intended to be inclosed in the casing C asillustrated, the casing I) may be in the nature of a union nut takingonto the end of the tube or casing C as shown; and in order to preventthe lifting out of knob 9', it may be provided with a projection or anannular flange is, which is larger in diameter than the diameter of theopening in the casing G through which the shank of member or knob jtakes, as clearly shown. It is apparent, that as knob j is turned, theeccentrically mounted projection z bearing against the cross-head 71.will press the upper end of lever f toward the left in Fig. 1, swinginglever on its pivot, thereby pressing the lower end of lever f againstvalve Z) and raising it from its seat, permitting the water to drainfrom the 'receptacle or basin A. The nature of the operating mechanism,that is the frictional contact between the cocentrically mounted cam zand cross-head h, will hold the valve in its raised position until theknob j is turned back to the position shown in Fig. 1, when lever f andvalve 7) will fall back to the normal or closed position by gravity, aswill be readily understood.

Where it is desired to have the operating member or knob mounted on thesplashboard above the slab or basin-top, I revolubly mount knob on thesplash-board E in any convenientmanner, as for example by having theshank take through nut Z, which is held in place by nut Z. Secured tothe inner end of the shank of knob is a cam m which is substantiallysemi-elliptical in shape as clearly shown in Fig. t. In thisconstruction lever f is provided at its upper end with the angularextension f, the up-- which the end of the lever takes when the cam isrotated, thereby holding the cam against automatically turning, holdinglever f in its tilted position until it is desired to close waste-valveZ), when knob j is turned in the reverse direction and with it cam m,thereby permitting the lever and valve to drop to normal or closedposition. In this construction the cam will prevent button or knob yfrom being withdrawn.

I have shown and described specific forms of my invention, but it isapparent that other modifications may be employed without departing fromthe spirit of my invention.

Having thus described my invention, what I wish to secure by LettersPatent, 1s:

1. In a device of the class described, the combination of a bowl, acasing separate from said bowl and secured to the bottom thereof bymeans of a perforated cap, said cap having a downwardly extending stem,said casing having an enlargement below said perforated cap, the bottomof said enlargement being shaped to form a valve seat, a valve held onsaid seat by gravity, and movable upward to release water in said bowl,said valve having a guide-way for the downwardly extending stem of saidperforated cap, said casing having a tubular opening at its lower endfor connection with a waste pipe, and a lever within said casing andpivoted thereto, said lever having a curved lower end engaging with thebottom of said valve and being movable upward to lift the valve againstthe pressure of water cap, the bottom of said enlargement being shapedto form a seat, a valve held on said seat by gravity and movable upwardto release water in said bowl, said valve having a guideway for thedownwardly extending stem of said perforated cap, said channel havingcommunication with a waste-pipe, and a lever within said channel andpivoted thereto at a place removed from the upper end, said lever havinga curved lower end engaging with the bottom of said valve and beingmovable upward to lift the valve against the pressure of water in thebowl.

3. In a device of the class described, the combination of a bowl, acasingv separate from said bowl and secured to the bottom thereof bymeans of a perforated cap, said cap having a downwardly extending stem,said casinghaving an enlargement below said perforated cap, the bottomof said enlargement being shaped to form a valve seat, a valve held onsaid seat by gravity, and movable upward to release water in said bowl,said valve having a guideway for the downwardly extending stem of saidperforated cap, said casing having communication with a waste-pipe, anda lever within said casing for operating said valve.

4. In a device of the class described, the combination of a channelarranged at the side of a bowl, a perforated cap affording communicationbetween said channel and the bottom of said bowl, said cap having adownwardly extendin stem, said channel having an enlargement below saidperforated cap, the bottom of said enlargement being shaped to form aseat, a valve held on said seat by gravity andmovable upward to releasewater in said bowl, said valve having a guideway for the downwardlyextending stem of said perforated cap, said channel having communicationwith a waste-pipe, and a lever within said channel for operating saidvalve.
